(If you have product planning, )I think that you should officially contact Renesas.

I am not a product planning representative.
I'm considering running cryptographic algorithms implemented on R-Car H3 on a boot loader on which Linux is not running.

I will concretely describe what I can not realize.

First, when ARM Trusted Firmware jumps to the address where the OP-TEE function exists, an exception will be raised.
After that, "plat_panic_handler" will be in infinite loop state.
I guess that it is probably guarded by MMU, but I do not know how to deal with it.

Second, About signature verification using key of RSA.
In order to register the key of RSA, I guess using functions like "alloc_rsa_public_key" and "alloc_rsa_keypair" in OP - TEE.
However, I do not know how to use functions such as arguments and procedures.
